Abstract

The analysis of stress-strain state non axis symmetric drawing process, which was developed based on an analytical model of the process. Obtained the dependencies for the components of the stress in the plastic region. The relationship between changes in the district velocity compressive stress on the peripheral area of the amount of shear stress. On this basis, it is given a numerical grade to increase the limit drawing ratio slightly different from equivalent value determined by the equality of the greatest meridional stress to the yield strength of the material at dangerous section of the blank.
